JAMES MARTZ, OF WINAMAO, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 240,155, dated April12, 1881.

Application filed February 1, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES MARTZ, a citizen of the United States,residing at Winamac, in the county of Pulaski and State of Indiana, haveinvented certain new and useful Improvements in Oar-Couplers; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters or figures of reference markedthereon, which form a part of this specification.

My invention relates to a car-coupling or coupling device for railroadcars; and the novelty consists in the construction and arrangement ofparts, as will be more fully hereinafter set forth, and specificallypointed out in the claim.

In carrying out my invention I secure in the adjacent draw-heads orbumpers a coupling-link. One of these links being in each draw-head, itwill be understood that they are locked by a gravital pin couplingtogether the cars, and that the links and draw-heads are adapted forefficient service in this art by a construction and arrangement whichwill allow the link of one draw-head, having beveled advancing end topass above or below the link in the adjacent draw-head, as will beexplained in this specification, and fully shown in the drawings;

It being understood that the coupling-links are. in duplicate, and thatduplex couplinglinks serve as the locking mechanism between the cars, inconnection with the gravital coupling-pins, the details of the inventionconsist, essentially, in the features and elements hereinafter specifiedand shown.

In carrying out the invention in detail I emply slotted duplex levershaving any convenient or desirable form and adaptation for the servicementioned, said levers being pivoted together, near their innerextremities, each to the truck-head, by a pin or boltwhich passesthrough the slot and is secured to such truck, and one of which carriesthe coupling-pin. The coupling-pin is hinged or pivoted in such a mannerthat the coupling-link of one car or truck will recede upon the pressureof the link of the adjacent car, and said pin does not engage the duplexlinks until such links have been forced past the pivot and the pingravitates between the links.

It will further be observed that the hanging coupling-pins are automaticcouplers, and that the slotted levers serve only as means for uncouplingor elevating the coupling-pins out of locking position with the links.

To enable others to construct and use my invention I will describe it indetail, reference being had to the accompanying drawings, which form apart of this specification, and in which similar letters indicate likeparts.

Figure 1 is a side elevation, partially-in section; Fig. 2. an end view,showing the levers and gravital locking-pin; and Fig. 3 is atop plan,and Fig. 4 a detached view, of the pivotal link.

Referring to the drawings, A represents the truck or car body, havingwheels to and an ordinary draw head, B, with flaring mouth I), andperforation c to receive a lock-pin, C, suspended in a vertical positionfrom the pivotal point (1 of levers D, having slots d, and pivoted tothe frame by bolts d operating through the said slots d.

E represents the coupling-link, pivoted in the draw-head B, as shown atc, and having beveled surfaces e. I

The slotted levers D are pivoted together upon their near innerextremities,-and approximately near this point is suspended the lockpin0, which operates in the longitudinal slot 1) as upon a pivot to lockthe adjacent link E within the draw-head B. The slotted levers D, whichsupport the lock pin 0, are curved laterally in such a manner that .thepin 0 will be afforded a longitudinal oscillatory motion from itspivotal point, operating through the slot 1).

I am aware of the construction shown in Patent No. 200,752, and do notbroadly claim such device. a

\Vhat I claim as new, and desire to secure by Letters Patent ot' theUnited States, is-

In a car-coupler, the draw-head B, in combination with the link E,pivoted therein, and beveled at e, and the pin 0, and levers D, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
